I tried out diving the 17s. I know from my concurrent French campaign that they can’t do more than about 225km without risking damage. But it’s hard to push a Halberstadt past 225 even with full throttle, short of going nearly vertical. The ac is soooooo draggy! And the problem when you do go vertical is then what? You’re on the hard deck and he’s still above you, spiraling down. To escape you need to dive and extend.
